# Terraform Consul Load Testing
|

Packer will output AMI IDs when it completes - save these AMI IDs as Terraform will require them later.
|
||||
The generated ami will have common tag `Environment = "consul-load-test"`.

For additional customization you can add [tags](https://docs.datadoghq.com/getting_started/tagging/assigning_tags/?tab=noncontainerizedenvironments) within the `scripts/datadog.yaml` file. An example of a tag could be `"consul_version" : "consulent_175"`. These tags are searchable through the datadog dashboard. Another form of customization is changing the datacenter tag within `scripts/telemetry.json`, however it is defaulted to `us-east-1`.
